Axis transfer:Get axis: GET
The actual axis transfer is performed with this
command. The channel for which the command is
programmed takes full responsibility for the axis.
Effects of GET:
Axis transfer with synchronization:
An axis always has to be synchronized if it has been
assigned to another channel or the PLC in the
meantime and has not been resynchronized with
"WAITP", G74 or delete distance-to-go before GET.
• A preprocess stop follows (as for STOPRE)
• Execution is interrupted until the transfer has
been completed.
Axis transfer without synchronization:
If the axis does not have to be synchronized no
preprocess stop is generated by GET.
Example:
N01 G0 X0
N02 RELEASE(AX5)
N03 G64 X10
N04 X20
N05 GET(AX5)
N06 G01 F5000
N07 X20
N08 X30
N09 ...
Automatic "GET"
If an axis is in principle available in a channel but is
not currently defined as a "channel axis", GET is
executed automatically. If the axis/axes is/are
already synchronized no preprocess stop is
generated.
